RMF7H2Y6–pr5018-D. Gray Whale (Eschrichtius robustus). Head is covered with barnacles (Cryptolepas rhachianecti) and cyamid whale lice.
RMRH077A–. Bulletin. Science; Natural history; Natural history. Fig. 7. Near terminally undercut, fully matured, Cryptolepas rhachianecti. a: Parapet was broken by authors. Notice cyamid-induced abrasions around periphery of barnacles, b: Parapet pulled back, revealing cyamids that had burrowed beneath the barnacle. This process ultimately relieves the sup- porting skin and the barnacle drops off the whale..

RMRH0784–. Bulletin. Science; Natural history; Natural history. cm. Fig. 6. Stages of scarification from terminal undercutting of Cryptolepas rhachianecti to complete dermal pigment transformation, a: A nearly completely undercut barnacle. The furrow excavated by feeding Cyamus scammoni is evident around its periphery. Basal excavation is also apparent, b: Site of a very recently removed barnacle. The fasicles of corium papillae that had grown between the barnacle's radial parapet flutes are apparent here as vertical structures. The object in the background is a penny, c: Characteristic scar created by
RMRH07D9–. Bulletin. Science; Natural history; Natural history. Scutum Parapet- Rostrum. Carina ^Operculum Tergum Fig. 1. a: A cluster of mature barnacles, Cryptolepas rhachianecti, from the rostrum of a gray whale (Table 1, WFS-1035). The apices of the scutae point in the general direction of maximum water-flow over the barnacle. The cirri of the barnacle in the upper right are extended through the open operculum. The identifiable cyamids are Cyamus scammoni. b: Cryptolepas rhachianecti, showing major anatom- ical features.. Please note that these images are extracted from scanned page images that may

RMRH076N–. Bulletin. Science; Natural history; Natural history. 122 SOUTHERN CALIFORNIA ACADEMY OF SCIENCES. Fig. 8. X-ray of four seed barnacles on the distal tip of the right pectoral fin of a yearling, male gray whale (Table 1, LACM-54549). attachment occurs. Initial attachment of the cypris larva of Cryptolepas rhachi- anecti has not yet been observed. Evidence based on the development and growth pattern of C rhachianecti, along with the analysis of specimens by means of cross- sections and x-rays (Figs. 5a, b, and 9) of "seed" barnacle-rich gray whale skin, show that juvenile barnacles (
